X font server does not like long PIDs

[Stephan A. Maciej]

Hi,

under Linux, you can set the maximum PID via doing

echo N >/proc/sys/kernel/pid_max

Typically, N is 32768, so that PIDs are 5 digits or less. The X font server 
relies on this and fails to daemonize if the decimal representation of 
getpid()'s return value is longer than 5 digits. The following patch fixes 
the problem for me. Diff is against xfs-1.0.4.
